In radio, we all know there is a big difference between a “promo” and a “commercial.”  While a radio promo is heard by many listeners to be a “commercial for the radio station,” radio people see this differently:

Commercial = Paid Advertiser Announcement

Promo = Some highly produced or prerecorded announcement about the radio station, either serious, fun or both.

Either way, we really do appreciate the irony of a “commercial” announcing that we are “not playing commercials.”
